Endobronchial high dose rate brachytherapy

International Journal of Radiation Oncology*Biology*Physics, 1993
Endobronchial brachytherapy for malignant airway obstructions has been used at several institutions using various radionuclides for decades. As small, high-activity, Iridium- 192 sources and remote afterloading systems became available, high dose rate (HDR) endobronchial irradiation became popular.

Prostate Brachytherapy: High Dose Rate

2012
Prostate cancer is the most common male malignancy in the Western world. Over the past decade, a significant shift has taken place in stage at diagnosis, with most patients now presenting with localized disease. Options for treatment include radical prostatectomy and different radiation modalities including external beam radiotherapy, low-dose-rate ...

High dose rate brachytherapy in the treatment of prostate cancer

World Journal of Urology, 2003
The optimal treatment of patients with localized prostate cancer remains controversial. Significant clinical data are available, however, demonstrating that patients treated with radiation therapy (RT) have a significantly better outcome as the dose to the gland is increased. What remains debatable, however, is how to best deliver these higher doses of

A plastic scintillation dosimeter for high dose rate brachytherapy

Physics in Medicine and Biology, 2006
In vivo dose verification in brachytherapy requires a small insertable dosimeter with a real-time readout capability. Fibre optic scintillation dosimeters, consisting of a plastic scintillator coupled to an optical fibre, are one of the most promising dosimeters for this application.

Biologic treatment planning for high-dose-rate brachytherapy

International Journal of Radiation Oncology*Biology*Physics, 2001
Interstitial brachytherapy treatment plans are conventionally optimized with respect to total target dose and dose homogeneity, which does not account for the biologic effects of dose rate. In an HDR implant, with a stepping source, the dose rate dramatically changes during the course of treatment, depending on location, as the source moves from dwell ...

High Dose Rate Brachytherapy of Localized Prostate Cancer

European Urology, 2002
We evaluated the safety and efficacy of high dose rate (HDR) brachytherapy using Iridium-192 (Ir 192) and 3D conformal external beam radiotherapy in patients with localized prostate cancer.A total of 444 patients with localized prostate cancer underwent combined radiotherapy with interstitial Ir 192 and 3D conformal external beam radiotherapy between ...

High-dose-rate interstitial brachytherapy for gynecologic malignancies

Brachytherapy, 2006
The study aimed to assess the outcome of locally advanced cervical and vaginal cancer treated with high-dose-rate interstitial brachytherapy (HDRB).Between 1998 and 2004, 16 previously unirradiated patients with locally advanced cervical and vaginal cancer not suitable for intracavitary brachytherapy because of distorted anatomy or extensive vaginal ...

Image‐guided high dose rate endorectal brachytherapy

Medical Physics, 2007
Fractionated high dose rate endorectal brachytherapy (HDR‐EBT) using CT‐based treatment planning is an alternative method for preoperative down‐sizing and down‐staging of advanced rectal adeno‐carcinomas. The authors present an image guidance procedure that was developed to ensure daily dose reproducibility for the four brachytherapy treatment ...

Lip cancer treatment with high dose rate brachytherapy

Radiotherapy and Oncology, 2003
We present 39 patients with lip carcinoma treated with HDR, (needles) with 5-5.5 Gy per 8-10 fractions b.i.d. (total dose 40.5-45 Gy).

High dose rate brachytherapy source measurement intercomparison

Australasian Physical & Engineering Sciences in Medicine, 2017
This work presents a comparison of air kerma rate (AKR) measurements performed by multiple radiotherapy centres for a single HDR 192Ir source. Two separate groups (consisting of 15 centres) performed AKR measurements at one of two host centres in Australia.
